> Shell.checkIsBashSupported swallowed an interrupted exception
> -------------------------------------------------------------
>
> Key: YARN-4467
> URL: https://issues.apache.org/jira/browse/YARN-4467
> Project: Hadoop YARN
> Issue Type: Bug
> Components: nodemanager
> Reporter: Wei-Chiu Chuang
> Assignee: Wei-Chiu Chuang
> Priority: Blocker
> Labels: oct16-easy, shell, supportability
> Attachments: HADOOP-12652.001.patch, YARN-4467.001.patch
>
>
> Edit: move this JIRA from HADOOP to YARN, as Shell.checkIsBashSupported() is
> used, and only used in YARN.
> Shell.checkIsBashSupported() creates a bash shell command to verify if the
> system supports bash. However, its error message is misleading, and the logic
> should be updated.
> If the shell command throws an IOException, it does not imply the bash did
> not run successfully. If the shell command process was interrupted, its
> internal logic throws an InterruptedIOException, which is a subclass of
> IOException.
> {code:title=Shell.checkIsBashSupported|borderStyle=solid}
> ShellCommandExecutor shexec;
> boolean supported = true;
> try {
> String[] args = {"bash", "-c", "echo 1000"};
> shexec = new ShellCommandExecutor(args);
> shexec.execute();
> } catch (IOException ioe) {
> LOG.warn("Bash is not supported by the OS", ioe);
> supported = false;
> }
> {code}
> An example of it appeared in a recent jenkins job
> https://builds.apache.org/job/PreCommit-HADOOP-Build/8257/testReport/org.apache.hadoop.ipc/TestRPCWaitForProxy/testInterruptedWaitForProxy/
> The test logic in TestRPCWaitForProxy.testInterruptedWaitForProxy starts a
> thread, wait it for 1 second, and interrupt the thread, expecting the thread
> to terminate. However, the method Shell.checkIsBashSupported swallowed the
> interrupt, and therefore failed.

> The original design is not desirable, as it swallowed a potential interrupt,
> causing TestRPCWaitForProxy.testInterruptedWaitForProxy to fail.
> Unfortunately, Java does not allow this static method to throw exception. We
> should removed the static member variable, so that the method can throw the
> interrupt exception. The node manager should call the static method, instead
> of using the static member variable.
> This fix has an associated benefit: the tests could run faster, because it
> will no longer need to spawn a bash process when it uses a Shell static
> method variable (which happens quite often for checking what operating system
> Hadoop is running on)
